Question

Quizplus · Accepted Answer

Wiping away the first drop of blood with a dry and clean gauze pad is an acceptable step during dermal puncture as it removes any tissue fluid or contaminants from the surface of the skin, which could alter the accuracy of the test results. Massaging the site can cause hemolysis and affect the quality of the specimen. Keeping the finger upright does not allow proper blood flow and can cause difficulty in collecting an adequate sample. Using an alcohol pad to wipe away the drop of blood can alter the results of certain tests, such as blood alcohol content.
